A system and method are provided for efficiently estimating vehicle tire wear. Vehicle kinetics (first) data are provided via one or more sensors associated with the vehicle and/or at least one associated tire. The vehicle kinetics data are locally processed to compress or otherwise generate second data as a reduced subset thereof, said second data representative of the first data and comprising any one or more predetermined wear-specific features extracted therefrom. The second data are selectively transmitted via a communications network to a remote computing system, which processes the second data to estimate a wear characteristic for the at least one tire. Alternatively, the second data processed to generate third data as a reconstruction of the first data, and the third data and the any one or more extracted features are processed to estimate a wear characteristic for the at least one tire.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, further comprising selecting a subset of the data frames between at least first and second events, and summarizing the data frames over a particular time or a particular distance.
3. The method of claim 1, wherein the step of processing the second data to estimate the wear characteristic for the at least one tire comprises, via the remote computing system, processing the second data to generate third data corresponding to the first data, and further processing the third data to estimate the wear characteristic for the at least one tire.
4. The method of claim 1, wherein the extracted features of the second data comprise wear performance characteristics representative of vehicle driving behavior.
5. The method of claim 1, wherein processing the first data comprises a Fourier transform on the first data and generating the second data comprising extracted relevant frequencies and associated amplitudes.
6. The method of claim 1, wherein the second data comprises aggregated data corresponding to an amount of time spent by the vehicle in each of one or more representative driving conditions.
7. The method of claim 1, wherein the selective transmittal of second data is event-based.
8. The method of claim 1, wherein the selective transmittal of second data is time-based.
9. The method of claim 2, wherein the summarizing of the data frames is performed via local processing at the computing system onboard the vehicle prior to transmittal of the summarized data frames to the remote computing system.
10. The method of claim 2, wherein the subset of the data frames are transmitted to the remote computing system and the summarizing of the data frames is performed via the remote computing system.
11. The method of claim 2, further comprising correcting for missing data in a summarized data frame by scaling the summarized data frame by an expected number of data frames with respect to an actual collected number of data frames.
13. The method of claim 12, further comprising a training process for the neural network layers wherein estimated wear values are compared to actual wear values for the at least one tire to generate an error value, and providing the error value as feedback to the neural network layers.
18. The method of claim 17, further comprising a training process for the neural network layers wherein estimated wear values are compared to actual wear values for the at least one tire to generate an error value, and providing the error value as feedback to the neural network layers.
